Lennerton, 27, and Miller, 26, are the oldest players added to the 40-man roster.

Lennerton batted .278 with 25 doubles, 17 home runs and 57 RBIs in 139 games last season. He was selected to the Futures Game last season and was awarded a Rawlings Minor League Gold Glove for his .996 fielding percentage.

“He’s hit and we feel he’ll be able to hit,” said assistant general manager Al Avila. “Hitting is a high commodity.”

Miller, who signed a minor-league deal with the Tigers after being released by the Rangers in September, split last season between Double-A Frisco and Triple-A Round Rock. Avila said Miller highly recommended by the team’s scouts.

Lobstein, 24, had a 3.27 ERA with 148 strikeouts in 1672⁄3 innings in 28 starts between Double-A Erie and Triple-A Toledo last season.

“We Rule 5’ed him and were able to make a deal for him,” Avila said. “We feel he’s very close to being able to help at the big league level.”

Fields, 22, hit .284 with 10 home runs and 58 RBIs in 118 games at Erie last season.

Suarez, 22, spent most of the last season at Erie and hit .253 with 24 doubles, nine home runs and 45 RBIs in 111 games. “We feel he can be an everyday middle infielder and feel he’s close to the big leagues,” Avila said.

Moya, 22, hit .255 with 12 home runs and 55 RBIs in 93 games at Lakeland last season.

“Moya’s upside is of an all-star potential,” Avila said. “Daniel Fields, same situation. We feel he’s got a high ceiling.”

Valdez, 23, split time between West Michigan and Lakeland last season. He had a 2.73 ERA in 27 games at West Michigan and a 2.74 ERA in 23 games at Lakeland.

“Here’s a young guy with a power arm that pitched very well last year that we feel can be a closer or set-up guy at the big league level that’s not too far away,” Avila said.

The Tigers couldn’t protect all of the players they have in their minor league system. Among those they did not protect are left-handed pitchers Kenny Faulk and Blaine Hardy, both of whom recently participated in the Arizona Fall League.

Faulk, 26, had a 6.97 ERA in 101⁄3 innings in the AFL. He had a 3.65 ERA with 52 strikeouts in 44.1 innings at Toledo last season.

Hardy, 26, had a 3.38 ERA in 16 innings with 16 strikeouts in the AFL. He was 8-3 with a 1.67 ERA and had 79 strikeouts in 912⁄3 innings between Erie and Toledo last season.
